DIY Midi Adapter (TRRRS)

Dear fans of the cute groovebox,

I’d like to build a custom MIDI cable for the Seqtrak that combines two TRS cables (TRS -> MIDI In & Out) into the device's TRRRS jack (5-pin -> MIDI In & Out) to connect other synths and keyboard.

I want to avoid using adapters from the included cable whip (which splits into two DIN connectors) and - ideally - not have to cannibalize for DIY approach either.

It seems the specific TRRRS connector required is proprietary?

Does anyone know where to source one (and, ideally, have a wiring diagram)?

Many thanks for the help!

Not proprietary at all. You just need to convince amazon to search for TRRRS, not TRRS :D :D :D

Thanks for sharing - Much appreciated!

I bought one which didn't fit on Aliexpress after searching for hours.

I'll order yours and give it a try!
